Description

Technical Field

[0001] The invention relates to the technical field of roll grinding, in particular to a high-precision roll grinding machine tool and a use method thereof. Background Art

[0002] In the manufacturing process of rollers, grinding is an essential part, which is usually completed with the help of roller grinders, which are a type of metal cutting machine tools.

[0003] When using the roll grinding machine, sufficient preparations must be made before operation, including cleaning the rolls and the machine table, installing and accurately aligning the rolls according to process requirements, then selecting a suitable grinding wheel and performing necessary dressing, setting the grinding parameters and starting the machine. The high-precision grinding of rolls requires improving the processing accuracy from multiple aspects. The grinding wheels used for grinding are generally divided into two types: rigid surface and flexible surface. The flexible grinding wheel evenly compensates for the error and thermal deformation of the roll during the grinding process through adaptive deformation.

[0004] However, during the grinding process, the heat generated by friction will cause the flexible grinding wheel substrate to expand and contract. When the temperature rises, the volume of the substrate expands, resulting in an increase in surface area, which in turn causes the grinding wheel surface to loosen and the fit with the workpiece to deteriorate. At the same time, the powder particles generated by grinding are easily scattered and retained at the contact interface between the grinding wheel and the workpiece due to lack of effective cleaning. These particles will embed into the tiny gaps between the two, causing unexpected grinding effects. The changes in the grinding wheel state caused by thermal expansion and contraction and the embedding effect of the powder particles are superimposed on each other, ultimately having an adverse effect on the processing accuracy.

[0013] As a preferred solution of the high-precision roller grinding machine tool described in the present invention, the conduction component includes a linkage block movably connected to the surface of the limit groove, a liquid storage box fixedly connected to the surface of the linkage block, an adapter base fixedly connected to the surface of the center plate, and a temperature transfer rod with one end fixedly connected to the surface of the liquid storage box and the other end passing through the surface of the adapter base.

[0014] As a preferred solution of the high-precision roller grinding machine tool described in the present invention, the adsorption component includes a plurality of transmission tubes fixedly connected to the surface of the liquid storage box and arranged in a linear array, an air bag fixedly connected to the surface of the transmission tube, an adsorption box fixedly connected to the surface of the adapter base, and an adsorption groove opened on the surface of the adsorption box.

[0015] As a preferred solution of the high-precision roller grinding machine tool described in the present invention, the interior of the adsorption box is slidably connected to a magnetic array substrate, the magnetic array substrate is fixedly connected to a plurality of magnetic balls arranged in a linear array, and the surface of the magnetic array substrate is fixedly connected to a vertical push rod located directly above the airbag.

[0018] According to a second aspect of the present invention, a method for using a high-precision roll grinding machine is provided, which is implemented based on any of the high-precision roll grinding machines described above, and the method comprises the following steps:

[0019] Step 1: Start the transmission system, the drive shaft starts to rotate, driving the centrifugal grinding structure to operate as a whole, and the right flange and the left flange form a stable transmission connection through the neck tube, providing initial power for centrifugal grinding;

[0020] In step 2, the driving shaft rotates at high speed to generate centrifugal force.

DETAILED DESCRIPTION

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it individually or selectively refer to an embodiment that is mutually exclusive of other embodiments.

[0040] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0041] Example 1, with reference to Figures 1-6, which is the first embodiment of the present invention, provides a high-precision roller 406 grinding machine, which includes a drive shaft 101; as the power core, the rotation of the drive shaft 101 provides initial power for the entire centrifugal grinding structure 200, ensuring the start and continuous operation of subsequent grinding actions.

[0042] The centrifugal grinding structure 200 includes a right flange 201 fixedly connected to the surface of the drive shaft 101, a neck tube 203 movably connected to the side of the right flange 201, a left flange 202 fixedly connected to the surface of the neck tube 203, mounting grooves 204 respectively provided on the surfaces of the left flange 202 and the right flange 201, and a centrifugal assembly 205 fixedly connected to the surface of the mounting groove 204; the side flange is fixedly connected to the drive shaft 101 and movably connected to the left flange 202 through the neck tube 203 to form a stable transmission frame, which not only transmits torque but also buffers vibration, providing basic support for the operation of the centrifugal assembly 205; the mounting groove 204 provides a fixed position for the centrifugal assembly 205 to ensure that the centrifugal assembly 205 works stably during rotation.

[0043] The conductive adsorption structure 300 comprises a central plate 301 movably connected to the surface of the neck tube 203, a carrier box 302 fixedly connected to the surface of the central plate 301 and positioned beside the centrifugal assembly 205, a mounting cover 303 fixedly connected to the surface of the carrier box 302, a conductive assembly 305 fixedly connected to the interior of the carrier box 302, and an adsorption assembly 306 fixedly connected to the conductive assembly 305. The central plate 301 movably connected to the surface of the neck tube 203 serves as a mounting base for the conductive and adsorption assembly 306. The carrier box 302 is fixed thereto and houses the conductive and adsorption components. The mounting cover 303 protects the internal structure, ensuring that the conductive and adsorption assemblies 305 and 306 operate in coordination to achieve heat transfer and particle adsorption.

[0044] The centrifugal assembly 205 includes a fixing block 2051 fixedly connected to the surface of the mounting groove 204 via rivets 2059, a positioning plate 2052 fixedly connected to the surface of the fixing block 2051, a first limiting rod 2053 movably connected to the surface of the positioning plate 2052, and a fixing bar 2058 rotatably connected to the first limiting rod 2053 and the surface of the positioning plate 2052. The fixing block 2051 is fixed to the mounting groove 204 via rivets 2059, and the positioning plate 2052 provides a mounting surface for the fixing block 2051. The first limiting rod 2053 is movably connected to the positioning plate 2052 and rotates via the fixing bar 2058. Under the action of centrifugal force, the fixing block 2051 expands outward, providing power for the radial movement of the sanding plate, ensuring that the sanding plate adapts to the surface of the roller 406.

[0045] A spring 2054 is fixedly connected to the surface of the first limiting rod 2053. The end of the spring 2054, away from the first limiting rod 2053, is fixedly connected to the second limiting rod 2055. A connecting plate 2056 is fixedly connected to the top of the second limiting rod 2055. Three connecting posts 2057, which extend through the surface of the carrier 302, are fixedly connected to the surface of the connecting plate 2056. The spring 2054 connects the first and second limiting rods 2055, utilizing its elastic properties to achieve dynamic adjustment and resetting of the sanding plate. The second limiting rod 2055 drives the connecting posts 2057 via the connecting plate 2056, transmitting centrifugal force to the sanding plate, maintaining a constant contact between the sanding plate and the roller 406.

[0046] Among them, a limiting groove 304 is defined on the surface of the middle one of the three connecting columns 2057. The ends of the three connecting columns 2057 away from the connecting plate 2056 are fixedly connected to the curved sanding plate 206. The left flange 202 and the right flange 201 are fixedly connected by bolts 2031. The limiting groove 304 in the middle of the connecting column 2057 provides space for the linkage of the conductive assembly 305, ensuring the stability of the sanding plate's movement. The curved sanding plate 206 adapts to the surface curvature of the roller 406, and the chamfered design at both ends prevents scratching the roller 406, thereby improving grinding uniformity and safety.

[0047] During use, the drive shaft 101 starts to rotate, driving the right flange 201 fixed thereto to rotate synchronously. The right flange 201 transmits the rotational force to the left flange 202 through the neck tube 203, causing the entire centrifugal grinding structure 200 to operate accordingly. The center plate 301 remains stable on the surface of the neck tube 203, providing a solid support for subsequent components. As the speed of the drive shaft 101 gradually increases, the centrifugal assembly 205 generates centrifugal force during rotation. The fixed block 2051 maintains a stable position in the mounting groove 204, and the positioning plate 2052 rotates accordingly. Under the action of centrifugal force, the first limiting rod 2053 moves outward along the surface of the positioning plate 2052, and the fixing bar 2058 rotates accordingly to adapt to its movement. The first limiting rod 2053 drives the second limiting rod 2055 to move outward synchronously through the spring 2054. The spring 2054 deforms during this process, and the second limiting rod 2055 is connected to the connecting plate 2056. The connecting column 2057 is pushed to move outward along the surface of the carrier box 302, and the connecting column 2057 drives the arc-shaped sanding plate 206 to gradually approach the surface of the roller 406 until the arc-shaped sanding plate 206 completely fits the surface of the roller 406 and performs the grinding operation. During this process, the elastic action of the spring 2054 enables the arc-shaped sanding plate 206 to always maintain appropriate pressure to fit the roller 406, and can adapt closely even if there are slight fluctuations on the surface of the roller 406. The chamfer design of the arc-shaped sanding plate 206 avoids causing additional damage to the surface of the roller 406 during grinding, ensuring a smooth grinding process.

[0048] As the speed of the drive shaft 101 gradually increases, the centrifugal force gradually increases, and the first limiting rod 2053 in the centrifugal assembly 205 expands outward on the surface of the positioning plate 2052. The spring 2054 fixed on its surface transmits the centrifugal force evenly to the second limiting rod 2055 through elastic deformation, driving the connecting plate 2056 to move synchronously. The three connecting columns 2057 slide stably on the surface of the carrier box 302, accurately transmitting the displacement to the arc-shaped sand plate 206, pushing the sand plate to move radially along the surface of the roller 406 and always closely fit, effectively coping with the problem of grinding wheel relaxation caused by thermal expansion and contraction. The elastic characteristics of the spring 2054 The adaptive bonding mechanism enables the sand plate to sense the tiny deformation of the surface of the roller 406 in real time, and maintains a stable contact pressure through dynamic adjustment, which not only effectively solves the problem of decreased adhesion caused by thermal expansion and contraction of the sand plate due to temperature changes, but also avoids the possible scratches on the surface of the roller 406 caused by the right-angle edge through the chamfered structure at both ends of the sand plate, ensuring the uniformity and safety of the grinding process. In addition, this adaptive bonding mechanism can automatically adapt to the surface curvature of rollers 406 of different specifications without the need for frequent adjustment of equipment parameters, significantly reducing production preparation time and manual intervention costs, and improving the versatility and production efficiency of the equipment.

[0049] Example 2, reference Figures 1-8 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: the conduction assembly 305 includes a linkage block 3051 movably connected to the surface of the limiting groove 304, a liquid storage box 3052 fixedly connected to the surface of the linkage block 3051, an adapter base 3054 fixedly connected to the surface of the center plate 301, and a heat transfer rod 3055, one end of which is fixedly connected to the surface of the liquid storage box 3052 and the other end of which extends through the surface of the adapter base 3054. The linkage block 3051 is movably connected to the limiting groove 304, ensuring that the liquid storage box 3052 moves synchronously with the connecting column 2057, allowing the heat transfer rod 3055 to stably transfer heat from the curved sanding plate 206 to the liquid in the liquid storage box 3052. The adapter base 3054 provides fixed support for the heat transfer rod 3055, ensuring the reliability of the heat conduction path and achieving real-time extraction of grinding heat.

[0050] Compared to Example 1, the adsorption assembly 306 further comprises a plurality of transmission tubes 3061 fixedly connected to the surface of the liquid reservoir 3052 and arranged in a linear array, an air bag 3062 fixedly connected to the surface of the transmission tubes 3061, an adsorption box 3064 fixedly connected to the surface of the adapter base 3054, and adsorption grooves 3065 defined on the surface of the adsorption box 3064. The transmission tubes 3061 are arranged in a linear array on the surface of the liquid reservoir 3052 and, when connected to the air bag 3062, form a gas conduction channel. When the air bag 3062 expands due to heat, it pushes the magnetic array substrate 3066 to move. The adsorption box 3064 is fixed to the adapter base 3054, and the adsorption grooves 3065 on its surface provide a centralized adsorption space for grinding particles, effectively preventing them from scattering.

[0051] Furthermore, a magnetic array substrate 3066 is slidably connected to the interior of the adsorption box 3064. Several magnetic balls 3067 arranged in a linear array are fixedly connected to the magnetic array substrate 3066. A vertical push rod 3063, located directly above the airbag 3062, is fixedly connected to the surface of the magnetic array substrate 3066. The magnetic array substrate 3066 is slidably connected to the adsorption box 3064. The magnetic balls 3067 arranged in a linear array on the surface are linked to the airbag 3062 via the vertical push rod 3063. When the airbag 3062 expands, the push rod pushes the substrate to move, causing the magnetic balls 3067 to approach the bottom of the adsorption tank 3065, forming a strong magnetic field area, which actively attracts the powder particles produced by grinding.

[0052] Furthermore, one end of the driving shaft 101 is fixedly connected to a moving box 401, and the surface of the moving box 401 is slidably connected to a guide rail 402, and the surface of the guide rail 402 is fixedly connected to a fixed base 403, and the surface of the fixed base 403 is fixedly connected to a working box 404. The driving shaft 101 drives the moving box 401 to slide along the guide rail 402, and the fixed base 403 supports the working box 404 and keeps the overall structure stable, so that the grinding device can accurately adjust its position to meet the processing requirements of different parts of the roller 406 and improve the processing flexibility. The surface of the working box 404 is clamped and fixedly connected to the roller 406, and the roller 406 The side of the fixed base 403 is fixedly connected to a pushing base 405, the surface of the mobile box 401 is fixedly connected to a cooling pipe 407, the surface of the mobile box 401 is fixedly connected to a cleaning rod 408, the working box 404 clamps the fixed roller 406 to ensure processing stability, and the pushing base 405 assists in adjusting the position of the roller 406; the cooling pipe 407 cools the equipment to reduce thermal damage; the cleaning rod 408 assists in cleaning residual particles, keeps the processing environment clean, and further improves processing accuracy. The working principle of this part is existing technology, and those skilled in the art can clearly understand it, so it will not be elaborated here.

[0053] During use, when the curved sanding plate 206 is in contact with the surface of the roller 406 for grinding under the action of centrifugal force, the connecting column 2057 moves synchronously with the sanding plate, and the limiting groove 304 on the surface of the middle connecting column 2057 drives the linkage block 3051 to move, and the linkage block 3051 then drives the liquid storage box 3052 to move accordingly in the carrier box 302. One end of the temperature transfer rod 3055 moves with the liquid storage box 3052, and the other end always contacts the curved sanding plate 206, continuously conducting the heat generated by grinding to the inside of the liquid storage box 3052.

[0054] As heat accumulates, the material in the liquid storage box 3052 is vaporized by the heat, and the generated gas enters the airbag 3062 through the transmission tube 3061, causing the airbag 3062 to gradually expand. The expanded airbag 3062 generates an upward thrust on the vertical push rod 3063 located directly above it, pushing the vertical push rod 3063 to move in the adsorption box 3064, thereby driving the magnetic array substrate 3066 to slide along the inner wall of the adsorption box 3064, and the magnetic ball 3067 on the surface of the magnetic array substrate 3066 moves along with it, gradually approaching the bottom of the adsorption groove 3065.

[0055] At this time, the magnetic field formed by the magnetic ball 3067 acts on the adsorption groove 3065 area, adsorbing the powder particles generated during the grinding process near the adsorption groove 3065, preventing the particles from scattering on the contact interface between the curved sand plate 206 and the roller 406. At the same time, the adapter base 3054 provides stable support for the temperature transfer rod 3055 and the adsorption assembly 306, ensuring the continuity of heat conduction and adsorption actions. The installation cover 303 protects the internal components and maintains the stability and order of the entire conduction and adsorption process.

[0056] The heat generated by grinding can be efficiently utilized to drive the operation of the subsequent adsorption structure, realizing effective energy conversion. The adsorption function can be triggered without an additional power source, thereby enhancing the economy and continuity of equipment operation. The realization of the adsorption function can timely adsorb and collect the powder particles generated by grinding, avoiding the particles from being scattered on the grinding interface to cause secondary damage or affect the grinding accuracy, reducing the adverse effects of impurities on the processed surface, and further ensuring the processing quality of the surface of the roller 406.

[0057] The remaining structures are the same as those of Example 1.

[0058] Example 3, reference Figures 1-11 , which is the third embodiment of the present invention, provides a method for using a high-precision roller 406 grinding machine tool, which is implemented based on the high-precision roller 406 grinding machine tool in any of the above embodiments, and includes the following steps:

[0059] Step 1: Start the transmission system, the drive shaft 101 begins to rotate, driving the centrifugal grinding structure 200 to operate as a whole. The right flange 201 and the left flange 202 form a stable transmission connection through the neck tube 203, providing initial power for centrifugal grinding, ensuring the smoothness and efficiency of power transmission, and providing a stable basic power for centrifugal grinding. The torque is transmitted through the rigid linkage between the right flange 201 and the neck tube 203, and the left flange 202 is synchronously driven to form a bidirectional stable support structure, ensuring that the centrifugal grinding structure 200 obtains uniform angular acceleration during the startup phase, eliminating the eccentric torque caused by traditional single-point transmission, significantly reducing equipment vibration and noise, and laying a dynamic balance foundation for subsequent precision grinding;

[0060] In step 2, when the driving shaft 101 rotates at high speed, a strong centrifugal force is generated. The first limiting rod 2053 and the second limiting rod 2055 in the centrifugal assembly 205 expand outward under the action of the centrifugal force, and the arc-shaped sand plate 206 is pushed to move radially along the surface of the roller 406 through the connecting column 2057. The elastic characteristics of the spring 2054 enable the arc-shaped sand plate 206 to dynamically adapt to the slight deformation of the surface of the roller 406 and always maintain a close fit, which not only solves the problem of decreased fit caused by thermal expansion and contraction, but also avoids scratches on the roller 406 by the right-angled edges due to the chamfered design at both ends of the sand plate. This adaptive lamination mechanism is compatible with the grinding requirements of rollers 406 of different specifications, reducing equipment adjustment costs. In addition, the uniform force distribution of the sanding plates reduces local wear and extends the service life of the sanding plates. The spring 2054 compensates for radial displacement in real time, allowing the three curved sanding plates 206 to wrap around the curved surface of the roller 406 with constant pressure. The chamfered edges of the curved sanding plates 206 form a continuous grinding zone during high-speed rotation, eliminating the stress concentration at the edges of traditional right-angled sanding plates and actively offsetting lamination failure caused by thermal expansion of the grinding wheel substrate through the centrifugal pressure self-regulation mechanism.

[0061] Step 3: The heat generated by grinding is transferred to the low-boiling-point liquid in the liquid storage box 3052 through the arc-shaped sand plate 206 and the temperature transfer rod 3055. The liquid vaporizes due to the heat, causing the air bag 3062 to expand. The expanded air bag 3062 pushes the vertical push rod 3063 to rise, driving the magnetic array substrate 3066 to move in the adsorption box 3064, so that the magnetic ball 3067 is close to the bottom of the adsorption groove 3065, realizing the real-time heat extraction and energy self-circulation, avoiding the performance degradation caused by overheating of the sand plate, and driving the adsorption by waste heat. The mechanism improves energy utilization efficiency. At the same time, the close connection between the liquid storage box 3052 and the temperature transfer rod 3055 ensures timely heat conduction, preventing heat accumulation from causing thermal damage to the sanding plate material. It also converts heat loss into adsorption driving force. The linear rise of the vertical push rod 3063 simultaneously drives the displacement of the magnetic array base plate 3066, forming a two-way linkage of thermal management and magnetic adsorption, realizing positive feedback control of grinding temperature and cleaning intensity. The higher the temperature, the stronger the magnetic adsorption effect, curbing the deterioration chain reaction caused by heat accumulation at the source;

[0062] In step four, the magnetic ball 3067 moves to the bottom of the adsorption groove 3065 to form a strong magnetic field area, which actively adsorbs the powder particles generated during the grinding process to prevent the particles from embedding in the contact interface between the arc sand plate 206 and the roller 406. At the same time, the spring 2054 resets and drives the arc sand plate 206 back to its original position, completing the grinding and adsorption cycle. This not only ensures the stability of the processing accuracy, but also reduces the frequency of equipment shutdown and cleaning due to the continuous cleaning of the contact surface, significantly reducing operating and maintenance costs. In addition, the activeness of magnetic cleaning avoids secondary damage to the sand plate surface caused by traditional cleaning methods, further improving the reliability of grinding quality. Moreover, the magnetic array substrate 3066 automatically shakes off the adsorbed particles when it moves downward, and cooperates with the lateral cleaning rod 408 to complete the self-cleaning cycle.
